You can have more than one simple subject in a sentence
When there is more than one verb in a sentence, it is called a compound verb. Each verb in a compound verb has its own subject and contributes to the overall meaning of the sentence.
Two or more subjects with the same verb is a compound subject.
The simple subject of the sentence 'One set of threads is called a warp' is 'set'.
There can be more than one subject in a sentence when the sentence has a compound subject, which consists of two or more subjects connected by a conjunction like "and" or "or." For example, in the sentence "Alice and Bob are going to the store," "Alice" and "Bob" are both subjects.
compound subject
No, a sentence can only have one simple subject, which is the main noun or pronoun that the sentence is about. Additional nouns or pronouns in a sentence would typically be part of a compound subject.
A group of words with a subject and a verb that does not form a complete sentence is called a sentence fragment. It lacks one or more essential elements to express a complete idea and may be missing a subject, verb, or both.

A compound subject is where there is more than one subject to a sentence.The best way to define this is through an example. In the sentence "Tom and Jerry ran," both Tom AND Jerry are the subject of the sentence. Since there are two subjects, this sentence has a compound subject.
A complete sentence contains a person, place or thing doing something. The person, place or thing is called the subject of the sentence. The "doing something" part of the sentence is called the action, predicate or verb. Traditionally, text books say that a complete sentence is one that contains both a subject and a predicate.
